Comparative Analysis of Financial Structures: An Application on the BIST Sustainability Participation Index Using the Mabac Method

This study aims to analyze the financial structure performance of companies listed in the Borsa Istanbul Sustainability Participation Index using the MABAC method based on 2023 data. Eight different financial ratios were used in the study, and all criteria were given equal weight. The difference of this study is that it focuses on an index (XSRDK) determined solely by sustainability and participation principles and analyzes the concept of sustainable financial structure within a multi-criteria decision-making framework. In the literature, MABAC has often been used in conjunction with objective weighting methods such as CRITIC and AHP. In this study, however, a more direct approach was adopted by assigning equal weight to all criteria. Additionally, this method, aims to provide investors and decision-makers with a comprehensive perspective. According to the findings, Galata Wind (A10) ranks first, followed by Akçansa Çimento (A1), Aksa Akrilik (A2), Margün Enerji (A16), and Esenboğa Elektrik (A9).
